Modules & Upstream Manufacturing

Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC standards and seek to guide manufacturers and investors on the best choice of materials – encapsulants in particular – when it comes to long term PID resistance.

This article talks about the areas the government needs to address both immediately and in the long run to help the ailing solar industry in the country.

France’s Sunbooster has developed a technology to cool down solar modules when their ambient temperature exceeds 25 degrees Celsius. The solution features a set of pipes that spread a thin film of water onto the glass surface of the panels in rooftop PV systems and ground-mounted plants. The cooling systems collect the water from rainwater tanks and then recycle, filter and store it again. The company claims the technology can facilitate an annual increase in power generation of between 8% and 12%.

The Asian Development Bank says developing countries in Asia and the Pacific should consider developing their own solar industry supply chains as the Covid-19 pandemic has exposed their over-reliance on China to carry through the energy transition.

Solar season had already started in the month of March. The demand for solar consumption is the highest during April-June quarter as summer picks up. This is the time when factory runs with full efficiency. India was estimated to install nearly 8 GW of solar panels in 2020, in which 90% consumption happens in utility-scale […]

Planning ahead is crucial to ensure the Indian solar industry bounces back quickly and the slowdown is not carried forward to 2021-22, say BloombergNEF analysts even as they estimate 75% fall in PV imports in the first quarter of year 2020 over the previous quarter and revise annual capacity addition forecasts.

Solar manufacturing’s recent move toward larger wafer/cells throws into focus the need for effective cell-cutting techniques to handle the processing of these cells into half cut or even smaller formats. pv magazine looks at the landscape for cell cutting, as the technology reaches maturity and moves into the mainstream of cell/module production.

A new, non-destructive technique has been proposed by researchers who say identifying early-stage discoloration in EVA encapsulants can help detect degradation in solar panels before power output is affected. The IIT Bombay group used an ultraviolet accelerated aging test during 34 days on three encapsulant samples.

U.S.-owned analyst Wood Mackenzie expects solar demand to decline but predicts the market will recover, with the prospects for the energy transition remaining intact.

Developers are also expected to drag their heels over project completion during the first half of the year as the safeguarding duty applied to imported Chinese and Malaysian solar products is due to expire at the end of July.
